Sandalwood vs. Aloeswood: the Two Woods that Define Japanese Incense

If you understand byakudan and jinkō, you understand 90% of Japanese incense. Here is what separates them — in scent, in price, and in what they ask of you.

The short version

Byakudan: the everyday classic

Sandalwood is the Santalum album tree, native to southern India. The heartwood is soft enough to carve and rich enough in fragrant oils that a single splinter, warmed in the hand, will scent an entire palm.

In Japanese incense, byakudan is the universal base. Almost every stick you burn will have some sandalwood in it, even when another wood (aloeswood, hinoki) is the star. Byakudan is what gives Japanese incense its characteristic "creaminess" — the warm, lactic softness that separates it from cedar-heavy Indian incense.

A stick that leans heavily on byakudan is best described as comforting. It does not demand your attention. It fills in the texture of a room the way a well-worn rug does.

Jinkō: the dark, rare heart

Aloeswood, also called agarwood, is something entirely different. It is not a species — it is a condition. When certain tropical trees in the Aquilaria genus are wounded (by insect, storm, or deliberate inoculation), they secrete a defensive resin into their own wood. Over decades, this resin saturates the heartwood and transforms it: denser, darker, heavier than water (which is why it's called "sinking wood" — jin-kō, 沈香 — because the best grades sink in water).

The scent of good jinkō is almost impossible to describe without sounding pretentious. The common notes — dark honey, damp leather, cool resin, a faint smoky coolness at the back — don't quite capture it. The experience of inhaling it is closer to tasting than to smelling.

Because it takes decades to form and cannot be farmed at scale, high-grade jinkō is scarce. Prices at the top end are measured in dollars per gram, and kyara — the most prized grade of jinkō, historically from a small region of Vietnam — routinely exceeds the price of gold.

How to choose between them

You don't. You use both, for different things.

• Burn byakudan in the morning, while working, while cooking, when guests arrive. It's the soft furnishing of your scent wardrobe.
• Burn jinkō in the evening, before meditation, when reading something difficult, when something important has happened (or nothing has and you want it to). It's the occasion wood.

A note on kyara

You will see the word kyara on some high-end Japanese incense. Treat it with skepticism. Most sticks labelled "Kyara" are jinkō-forward blends that contain some kyara; true kyara-chip incense is sold by grams, in a wooden box, with provenance documentation. Neither category is a starting point — come back to this question after you've spent six months with basic byakudan and basic jinkō.
